Too Heavy, Elephant! by Oxford Children's Books (author) and Tony Neal (illustrator)

Elephant is too heavy to play with Mouse on the seesaw. Their friends can help, but will it be enough to get Elephant’s feet off the ground? A great deal (of Elephant) hangs in the balance in this hilarious introduction to the maths concept of weight. With engaging artwork and a very funny story, readers won’t even realize that they’re learning something while they laugh along with the animal friends! Features fun activities at the back to explore the topics further.
